4:30pm: The Astros have issued the following statement regarding the leaked notes:

“Last month, we were made aware that proprietary information held on Astros’ servers and in Astros’ applications had been illegally obtained. Upon learning of the security breach, we immediately notified MLB security who, in turn, notified the FBI.  Since that time, we have been working closely with MLB security and the FBI to the determine the party, or parties, responsible.  This information was illegally obtained and published, and we intend to prosecute those involved to the fullest extent.

“It is unfortunate and extremely disappointing that an outside source has illegally obtained confidential information.  While it does appear that some of the content released was based on trade conversations, a portion of the material was embellished or completely fabricated.”

2:29pm: Extensive trade discussion notes, apparently logged by Astros executives about their talks with other teams, have been leaked onto the site AnonBin here and here, with Deadspin breaking the story and Yahoo’s Jeff Passan verifying the authenticity of the logs.  The earliest notes are from June 2013, and the latest are from March of this year.  The Astros have yet to comment on the leak, which provides unprecedented detail into how the team values players and approaches trade discussions.  According to ESPN’s Buster Olney, the Astros have been reaching out to people around baseball apologizing for the leaks, and plan to issue a statement soon.

A March feature by Evan Drellich of the Houston Chronicle outlines Ground Control, the Astros’ confidential internal database from which the trade discussion notes were likely taken.  At this time, it’s unclear whether the information reached the Internet via a rogue employee of the team, or by some kind of security vulnerability in Ground Control.  The trade discussion information, mostly from last summer and offseason, is somewhat dated in the fast-moving baseball hot stove world.  The larger ramification is the breach of trust experienced by the many non-Astros executives cited in the notes.  It’s unlikely any team would rule out the Astros as a trading partner based on this breach, but some teams could approach talks with added caution.  Additionally, I imagine the many other teams with such highly sensitive material online are doubling down on security right now.

The Astros’ trade notes from last summer and offseason range from the blockbuster to the mundane; here are some highlights.

• On November 15th, Astros GM Jeff Luhnow expressed interest with Marlins GM Dan Jennings in slugger Giancarlo Stanton.  From the notes: “[Jennings] said he doesn’t think he’ll trade Stanton and the only deal he could think of from us that would work would be [George] Springer and [Carlos] Correa. [Luhnow] said that would not work. [Luhnow] posited a deal around [Jarred] Cosart and [Delino] DeShields.”  It’s not a big surprise that Luhnow rejected Jennings’ proposal out of hand, as Correa and Springer were ranked #4 and #19 on Keith Law’s top 100 prospects list for ESPN, and are major building blocks for Houston.  That Luhnow didn’t appear to offer either player suggests he was mostly gauging Stanton’s price after an off-year with three years of control remaining.  UPDATE: Jennings has commented to Bob Nightengale of USA Today, saying it’s fabricated that they ever offered Stanton to the Astros or any other team, also using the word “laughable.”
• Interest in Astros catcher Jason Castro was strong last offseason, with a few surprising suitors.  The Blue Jays and Rangers reached out in mid-October to gauge Castro’s price, the White Sox had “definite high interest,” and Mariners GM Jack Zduriencik told Luhnow in November that he was getting calls from other teams asking if he could get Castro from the Astros for those teams.  Zduriencik offered Dustin Ackley and was turned down.
• Notes for the Astros’ summer trade discussions begin at June 17th, 2013.  The team ultimately went on to acquire Ronald Torreyes from the Cubs in June, and also dealt veterans Jose Veras, Bud Norris, and Justin Maxwell near the July deadline.  The Astros did not end up acquiring any top 100-type prospects, but they sure did ask for the moon.  For Norris, the Astros sought Kyle Crick and Clayton Blackburn from the Giants, Dylan Bundy or Kevin Gausman from the Orioles, Marcus Stroman and more from the Blue Jays, Xander Bogaerts, Allen Webster, Jackie Bradley Jr., or Garin Cecchini from the Red Sox, and Tyler Glasnow plus Luis Heredia or Nick Kingham from the Pirates.  The Red Sox offered Ryan Lavarnway or Deven Marrero for Norris and were turned down.  In the end, the Astros traded Norris and an international draft slot to the Orioles for L.J. Hoes, Josh Hader, and a 2014 competitive balance pick.
• When Nationals GM Mike Rizzo called to express interest in middling Astros starting pitcher Lucas Harrell, who had a 5.17 ERA at the time and nearly as many walks as strikeouts, “[Luhnow] told him we would still need a headliner like [Lucas] Giolito because we still value Harrell highly. Rizzo did not respond immediately.”
  Harrell was designated for assignment, outrighted, and traded for a pittance nine months later, so the Astros might have overplayed their hand.
• “Untouchable” players from other teams were revealed through conversations with their executives.  White Sox GM Rick Hahn wouldn’t consider trading Chris Sale, Jose Quintana, Jose Abreu, or Avisail Garcia.  Blue Jays GM Alex Anthopoulos considered Brett Lawrie off-limits.  Pirates outfield prospect Gregory Polanco came up as well, in that GM Neal Huntington wouldn’t include him in any Norris deal.  In December talks regarding Harrell, the Giants said they would not discuss Brandon Belt.
• More random notes: Mets executive Paul DePodesta asked Luhnow if the Astros would consider trading shortstop Jonathan Villar in a Daniel Murphy deal in December…the Marlins expressed interest in Jose Altuve, Matt Dominguez, and others in December.
